result in a single frame. Management information is specified only once per frame; therefore, the ratio of
payload data to the total volume of data is higher, resulting in greater throughput.
Note
You can configure radio settings for all APs in a device group from the device group Radio tab
and Advanced Radio dialog. And you can override radio settings for one or more individual
APs from the AP

Description
OCS Channels
Note: Supported on AP5xx models only.
Define custom channel list:
•
Channels for Radio 1 are all 2.4GHz or 5GHz lower band channels.
Channel width is selectable.
•
Channels for Radio 2 are 5GHz channels or 5GHz upper band
channels. Channel width is selectable.
Aggregate MPDUs
Determines MAC Protocol Data Unit (MPDU) aggregation. Enable to
increase the maximum frame transmission size, providing a significant
improvement in throughput.
LDPC
Increases the reliability of the transmission resulting in a 2dB increased
performance compared to traditional 11n coding.
STBC
Space Time Block Coding. A simple open loop transmit diversity
scheme. When enabled, STBC configuration is 2x1 (two spatial streams
combined into one spatial stream). TXBF overrides STBC if both are
enabled for single stream rates. Enable this setting when you
anticipate single stream clients with lower RSS power.
Disassociate on Low RSS
Forces clients with low RSS to disassociate from an AP radio. This
setting is configured per radio. A client is forced off an AP radio when
RSS is measured at 5dBm below the Probe Suppression RSS
Threshold. Enabling this option forces client to roam to a better AP for
improved network performance. This setting is not supported on
ExtremeWireless WiNG APs, and it is always disabled by default.
Probe Suppression on Low RSS
Reduces the number of probe responses by preventing clients with
low RSS from associating with an AP radio. This setting is configured
per radio. Clients with RSS measured below the Probe Suppression
RSS Threshold will not associate with the AP. This setting is disabled
by default.
Probe Suppression RSS Threshold
Determines the RSS threshold for forced disassociation and probe
suppression. The default threshold is -90 dBm. Valid value range is
-50dBm to -100dBm.
TX Beam Forming
Tx Beam Forming is a technique of re-aligning the transmitter
multipath spatial streams phases in order to get better signal-to-noise
ratio on the receiver side. For the For the 39xx APs, this setting is only
available on the 5GHz radio. The valid values are: MU_MIMO and
Disabled. For AP76xx and AP8xxx, this setting is available on both
radios. The valid values are: SU_MIMO and MU_MIMO.
